How is Zeke surviving in Sam's meat suit?

Back when the show introduced the idea of angels needing a vessel, it was made clear that if an angel didn't find an appropriate vessel of a certain bloodline, they wouldn't be able to survive in the body for long. Not only did the human have to be of a certain bloodline, but each angel had its own bloodline to follow, sometimes leaving the winged ones with slim pickings when it came to vessels.

So how is it then that Ezekiel has possessed Sam (Jared Padalecki) without any adverse effects? In fact, in the sneak peek preview for the next episode, both Sam and Zeke seem to be doing really well. One explanation could be that, as Lucifer's vessel, Sam's body has the ability to host any angel. Or it could be the way that Zeke is possessing Sam that's the answer. Perhaps by only staying in the background and not running the show unless absolutely necessary, Ezekiel is able to heal Sam without burning him from the inside out.

When will Castiel find Sam and Dean?

The idea of Castiel (Misha Collins) becoming human and having to deal with the discomforts that come with such a condition is one that fans have been anticipating for many seasons. While there were some hints of HumanCas in Season 5, this is the first time that he's truly been, for all intents and purposes, human. From the preview, it looks like Castiel will still be on his own during the next episode, but many fans are wondering when he'll meet up with his earthly brothers.

It could be that the writers want to give Castiel even more challenges now that he's human. While it's true that it might be a tad funnier to see Cas with the Winchesters as he figures out the intricacies of being truly flesh and bone, there's something to be said for watching him figure those things out on his own. At some point, though, the novelty will wear off and that's when fans will want Castiel to join Sam and Dean (Jensen Ackles). The only question now is: When will that happen?

Is Crowley partially human?

Happily, Crowley (Mark Sheppard) not only survived the Trials that Sam nearly completed, but he also came through them with the same witty/surly attitude. One thing that isn't entirely clear yet is whether or not a piece of those Trials stuck with him. In Episode 2, Crowley compelled Kevin to beat the living daylights out of him. He claimed later that he did it for the enjoyment of seeing Kevin lose control, but there could be another explanation.

Could it be that Crowley wanted Kevin to punish him for the heinous crimes he committed as a demon? In the same episode, Crowley seemed to have flashbacks to the moments during Sam's attempted "cure" when Crowley's demon walls began to fail and the human side returned — with plenty of pain and guilt to go with it. Has Crowley kept a piece of humanity from the Trials and if so, how will that change the King of Hell?
